4.3 Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your finger on

the switch or plugging in tools that have the switch on
invites accidents.

4.4 Remove adjusting keys or wrenches before
turning the tool on. A wrench or a key that is left

attached to a rotating part of the tool may result in
personal injury.

4.5 Do not overreach. Keep proper footing and bal­ance at all times. Proper footing and balance enable

better control of the tool in unexpected situations.

4.6 Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety shoes, hard hat

or hearing protection must be used for appropriate con­ditions.

5 Tool Use and Care

5.1 Use clamps or other practical way to secure and
support the workpiece to a stable platform. Holding

the work by hand or against your body is unstable and
may lead to loss of control.

5.2 Do not force tool. Use the correct tool for your
application. The correct tool will do the job better and

safer at the rate for which it is designed.

5.3 Do not use tool if switch does not turn it on or
off. Any tool that cannot be controlled with the switch is

dangerous and must be repaired.

5.4 Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing the tool. Such preventive

safety measures reduce the risk of starting the tool
accidentally.

5.5 Store idle tools out of reach of children and
other untrained persons. Tools are dangerous in the

hands of untrained users.

5.6 Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools with sharp

cutting edges are less likely to bind and are easier to
control.

5.7 Check for misalignment or binding of moving
parts, breakage of parts, and any other condition
that may affect the tool’s operation. If damaged,
have the tool serviced before using. Many accidents

are caused by poorly maintained tools.

5.8 Use only accessories that are recommended by
the manufacturer for your model. Accessories that

may be suitable for one tool may become hazardous
when used on another tool.

6 SERVICE

6.1 Tool service must be performed only by
qualified repair personnel. Service or maintenance

performed by unqualified personnel could result in a
risk of injury.

6.2 When servicing a tool, use only identical
replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unau-

thorized parts or failure to follow maintenance instruc­tions may create a risk of electric shock or injury.

GENERAL SAFETY RULES

1 WARNING! Read and understand all instructions. Failure to follow all instructions listed below may

result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS.

2 Work Area

2.1 Keep your work area clean and well lit. Cluttered

benches and dark areas invite accidents.

2.2 Do not operate power tools in explosive atmos­pheres, such as in the presence of flammable liq­uids, gases, or dust. Power Tools create sparks which

may ignite the dust or fumes.

2.3 Keep bystanders, children, and visitors away
while operating a power tool. Distractions can cause

you to lose control.

3 Electrical Safety

3.1 Grounded tools must be plugged into an outlet
properly installed and grounded in accordance with
all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do
not use any adapter plugs. Check with a qualified
electrician if you are in doubt as to whether the
outlet is properly grounded. If the tools should elec-

trically malfunction or break down, grounding provides
a low-resistance path to carry electricity away from the
user.

Applicable only to Class I (grounded) tools.

3.2 Double insulated tools are equipped with a
polarized plug (one blade is wider than the other).
This plug will fit in a polarized outlet only one way.
If the plug does not fit fully in the outlet, reverse the
plug. If it still does not fit, contact a qualified
electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation

eliminates the need for the three-wire grounded power
cord and grounded power supply system.

Applicable only to Class II (double insulated) tools.

3.3 Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if your body
is grounded.

3.4 Don’t expose power tools to rain or wet
conditions. Water entering a power tool will increase

the risk of electric shock.

3.5 Do not abuse the cord. Never use the cord to
carry the tools or pull the plug from an outlet. Keep
cord away from heat, oil, sharp edges or moving
parts. Replace damaged cords immediately.

Damaged cords increase the risk of electric shock.

3.6 When operating a power tool outside, use an
outdoor extension cord marked “W-A” or “W”.

These cords are rated for outdoor use and reduce the
risk of electric shock.

4 Personal Safety

4.1 Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use tool while tired or under the influence of
drugs, alcohol or medication. A moment of

inattention when operating power tools may result in
serious personal injury.

4.2 Dress properly. Do not wear lose clothing or
jewelry. Contain long hair. Keep your hair, clothing
and gloves away from moving parts. Loose clothes,

jewelry or long hair can be caught in moving parts.

Before using a grinder or installing a new
wheel, inspect the grinding wheel for
chips and cracks. Remove bad wheels
immediately. Run the tool at no load for
one minute, holding the tool in the
direction away from people. Wheels with

flaws will normaly break apart during this
time.

Carefully handle both the tool and
individual grinding wheels to avoid
chipping or cracking. Install a new wheel
if tool is dropped while grinding. Do not
use a wheel that may be damaged.

Fragments from a wheel that bursts during
operation will fly away at great velocity
possibly striking you or bystanders.

Warning! Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals
known to cause cancer, birth defects or
other reproductive harm. Some examples of
these chemicals are:
– Lead from lead-based paints,
– Crystalline silica from bricks and cement

and other masonry products, and

– Arsenic and cromium from chemically

treated lumber.

Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equipment,
such as dust masks that are specially
designed to filter out microscopic particles.

A damaged or cracked side handle must be
replaced. Never operate a machine with a
defective side handle.

SPECIFIC SAFETY RULES

Caution: Hold tools by insulated gripping
surfaces when performing an operation
where the tool may contact hidden wiring or
its own cord. Contact with a live wire will make

exposed metal parts of the tool "live" and shock
the operator.

Wear ear protectors when using the tool for
extended periods. Prolonged exposure to high

intensity noise can cause hearing loss.
Always wear eye goggles and hearing protection.

Use other available protective equipment such
as protective gloves, suitable protective work
clothing and helmet.

During machining, of metals

in particular, conductive
dust can form deposits

inside the machine. This
can lead to the transfer of electrical energy onto
the machine housing. This can mean a
temporary danger of electric shocks. This is why
it is necessary when the machine is running to
blow compressed air through the rear ventilation
slots of the machine regularly, frequently and
thoroughly. Here, the machine must be held
firmly.

It is recommended to use a stationary extraction
system and to place a ground fault circuit
interrupter (GFCI) downstream.

If the angle grinder is deactivated by the GFCI
circuit interrupter, the angle grinder must be
checked and cleaned. Cleaning the motor, see
Maintenance.

Ensure that sparks produced during work do not
constitute a risk to the user or other personnel
and are not able to ignite inflammable
substances. Endangered areas must be
protected with flame-resistant covers. Make sure
that fire-risk areas are always provided with
suitable fire extinguishers.

If operating the power tool in damp locations is
unavoidable, a Ground Fault Circuit Interrupter
must be used to supply the power to your tool.
Electrician´s rubber gloves and footwear will
further enhance your personal safety.

When using grinding wheel attachments, the
guard must always be attached to the tool and
positioned for maximum safety, so the least
amount of wheel is exposed from the side the
tool is being operated.

Grinding wheels or any other accessory must
have a maximum safe operation speed greater
than the “no load RPM” marked on the tool´s
nameplate.

Always use auxiliary handle for maximum
control over torque reaction or kick-back.

Operation of the grinder without the side handle
could cause loss of control of the grinder,

Recommended Minimum Gage for Cord Extensions for Portable Electric Tools

Gage sizes in shaded areas are normally not available as flexible extension cords.

USE PROPER EXTENSION CORD

Make sure your extension cord is in good condition. When using an extension cord, be sure
to use one heavy enough to carry the current your product will draw. An undersized cord will cause
a drop in line voltage resulting in loss of power and overheating. The table below shows the correct
size to use depending on the cord length. If in doubt, use the next heavier gage. The smaller the
gage number, the heavier the cord.
